DRAWER ASSEMBLY This application is a continuation-in-part of application Serial No. 776,070, filed on Nov. 15, 1968, now abandoned.

This invention relates to a drawer assembly and to methods for producing the assembly.

In the construction of homes, cabinets are invariably located in the kitchen and in other rooms. Cabinet makers attempt to build the cabinets of uniform dimensions for purposes of efficiency; however, it is often necessary to vary these dimensions because of architectural variations of different homes.

The provision of drawers for location within a cabinet housing often requires the construction of drawers which are of varying dimensions depending upon the size of the cabinet. In many instances, the pieces required for the construction of a drawer are individually cut, and drawers built in. Where standard drawer sizes are employed, the cabinet construction must either conform with these sizes or the standard drawers must be modified to fit cabinet variations.

It is the general object of the instant invention to provide an assembly consisting of a frame and associated drawers which can be economically produced irrespective of the dimensions of cabinets or other areas where the assembly is to be installed, the assembly comprising a self-supporting and self-contained unit.

It is a more specific object of this invention to provide an assembly of the type described which is characterized by structural members designed so that simple cutting operations can be employed for changing the size of the members whereby an assembly produced with the members can have widely varying dimensions without in any way affecting the manufacturing cost.

It is a still further object of this invention to provide a method for producing an assembly of the type described.

It is an additional object of this invention to provide a track structure which can be associated with a frame, of the type referred to, or with existing surrounding structure, the track structure providing highly efficient means for movably mounting a drawer, and also providing means cooperating with a drawer to permit easy insertion and removal of the drawer relative to the surrounding structure while also providing stop means limiting movement of the drawer during use.

These and other objects of this invention will appear hereinafter and for purposes of illustration, but not of limitation, specific embodiments of the invention are shown in the accompanying drawing in which:

FIG. 18 is a cross sectional view taken about the line 18-18 of FIG. 17.

The construction of this invention generally comprises an assembly of drawers wherein each drawer includes opposed side walls, a bed portion and front and back walls. The drawers are supported in a frame which includes upstanding corner posts and bottom connecting members extending between corner posts at the front and back of the assembly. Additional longitudinally extending connecting members are located along each side of the assembly suspended between the corner posts. These longitudinally extending members include integrally formed tracks adapted to receive the lower edges of the side walls of the drawers for providing sliding movement of the drawers relative to the frame.

The invention also relates to track means ofa unique design which may provide the longitudinally extending members referred to or which may be associated with other existing structural members to provide support for drawers. The tracks and drawers are designed so that stop means which determine the extent of allowable movement for a drawer can be efficiently built-in. The design of the tracks and stop means is such that the drawers can be very easily located in place and removed whenever desired.

In the construction of the assembly, the bed of the drawers may be formed from fiberboard material which can be obtained as elongated sheet stock. The sheet is scored by providing a V-shaped groove adjacent each side, and the sides are then bent up to provide front and back walls. The sheet stock can then be cut into individual sections with-the width of each section depend ing upon the particular size requirement. The transversely extending frame connecting members are also formed from elongated stock so that these connecting members can be cut to any desired length. The result is that the operations required for producing drawers of any size are identical and, therefore, extra cost is not involved when meeting unusual size requirements.

The drawer design may alternatively comprise separate front, back and side members. The front and back members are designed for efficient production in that cutting of extruded lengths into individual sections comprises the only manufacturing operations required for these drawer portions. The front portion includes an integrally formed handle, and the side walls are designed for insertion of the front and back portions along with a bottom wall portion, this assembly operation being carried out in a highly efficient manner.

FIG. 1 illustrates a drawer assembly characterized by the features of this invention. The assembly includes upstanding comer posts 12, and transversely extending bottom connecting members 14. Additional connecting members 16 extend longitudinally of the assembly.

As shown in FIG. 2, the corner posts 12 are formed from L-shaped tubing stock. This stock may be extruded aluminum which can be obtained in elongated form and cut to desired lengths, depending upon the height of the assembly to be produced. The connecting members 16 may also comprise an extruded shape which can be attached to the posts 12 by means of rivets 18. Naturally, connecting means such as screws, and welding, piercing and crimping, and adhesive techniques may also be employed. The members 16 define an integrally formed extension which provides a track 20 for supporting drawers 22. These drawers include side walls 24 defining a lower edge 26 which is received in the track 20.

The side walls 24 define grooves which include a central portion 28 and upwardly extending front and rear portions 30 and 32. An extension 34 is formed as a continuation of the groove portion 30. The grooves are preferably routed into the side walls. The side walls may comprise a fiberboard material or any other material having satisfactory strength, such as, vacuum formed or extruded plastic, sheet metal or wood.

The bed of each drawer is provided by means of a sheet 36 which may also be formed of fiberboard. As best shown in FIG. 7, the sheet 36 may be scored at 38 and 40, for example by cutting a V-shaped groove in the sheet. The end pieces 42 and 44 can then be folded upwardly to provide front and back walls for the drawer. The side edges of the sheet are received in the groove portions 28, 30 and 32 defined by the side walls 24 (FIG. 5).

A pair of pins 46 and 48 are secured to each side wall with the ends of the pins extending outwardly. The connecting members 16 include an upper flange 50, and the pins 46 and 48 are located beneath this flange in the normal position of the drawer. As shown in FIGS. 1 and 6, the flange 50 defines a pair of openings 52 and 54. When the pins 46 and 48 are aligned with these openings, a position slightly forward of the closed position of the drawers, the drawers can then be moved relative to the members 16 for assembly or removal purposes.

FIG. 4 illustrates an alternative to the use of pins 46 and 48 wherein a pin 55 is provided in a casing 57 with the casing being received in an opening defined in the side wall 24. The pin is normally urged outwardly by means of a spring 59 located within the casing. A knurled knob 61 is provided as an extension of the pin so that the pin can be pulled inwardly in opposition to the spring. In this position, the pin will clear the corner post 12 for removal of a drawer by pulling the drawer directly out. The openings 52 and 54 are not required with this arrangement. It is also contemplated that the pins 46 and 48 could be utilized without the openings 52 and 54 if removable drawers are not required.

The pins 46 and 48 (or pins 55 if these are employed) also serve as limit means for determining the fully open and fully closed positions of the drawers. Thus, the pins 46 will engage one leg of the posts 12 when the drawer is pulled outwardly to thereby prevent the drawer from being pulled away from the frame. Similarly, the pins 48 limit the rearward movement of the drawers. Instead of providing a pair of pins on each side of a drawer, one

pin could be located on each side in staggered relationship so that one will act as forward limit means and the other as a rearward limit means.

FIG. 8 illustrates comer joint means 56 which are preferably employed in the construction. The joint means 56 include L-shaped extensions 58 which are dimensioned to be received in the hollow interiors of the tubular posts 12 and the tubular connecting means 14. A press fitting arrangement may be provided with this design or the tube ends could be crimped for securing the elements together. The use of joint means 56 permits the use of connecting means 14 of varying lengths depending upon the design width for a drawer. Angle members or other solid lengths could instead be bent into U-shaped sections as substitutes for the members 12, 14 and 56.

A handle 60 is attached at the upper edge of the front wall 42. A tongue and groove connection 62 is provided for locating the handle 60, and adhesive may also be employed for holding these members together. The handle is beaded as shown at 64 to provide a satisfactory grip.

In the manufacture of the drawers of this invention, an elongated piece of sheet stock 36 is first scored as illustrated in FIG. 7, and adhesive is applied in the V- shaped grooves 38 and 40. The ends 42 and 44 are then bent upwardly. Either immediately before or immediately after this bending operation, the sheet stock can be cut into the desired width of the drawers being manufactured. The handle means 60 may be attached as an elongated member before the cutting operation or individual handle lengths may be attached after cutting. The side walls 24 are then brought into position, and these side walls serve as clamp means during setting of the adhesive applied in the V-shaped grooves. This arrangement greatly facilitates the over-all manufacturing operations since it minimizes the necessity for very accurate routing operations or accurate positioning of the walls 42 and 44 relative to the bed portion. Thus, these parts will be fit together before the adhesive sets so that deviations can be accommodated.

It will be appreciated that the above represents a preferred method of drawer manufacture, however, conventional drawer constructions could also be used in the assembly. For example, a drawer could be formed in a molding operation and then located in the assembly, however, the described technique is superior from the standpoint of cost and quality.

The frame members l2, l4 and 16 can be easily assembled, and in this connection, the length of the members 14 will be determined by the desired width of the drawers. The drawers 20 can be located after the frame is put into its desired final position or the entire assembly may be completed before being located in position.

The construction of this invention is particularly advantageous for use since the entire assembly 10 can be put into place in spaces of a wide variety of dimensions. In this connection, the assembly is useful for new construction as well as being useful as a self-supporting and self-contained unit which can be located to provide drawers in areas of older constructions, for example, in cabinets in existing homes.

As shown in FIG. 6, a double sided adhesive strip 66 with a removable masking strip may be located on the bottom of the members 14 to facilitate positioning of these members on a supporting floor. The selfcontained unit is also particularly useful for hanging from a wall or ceiling without the need for any surrounding enclosure on a supporting floor.

When being located during the construction of new cabinets, the corner posts may be positioned against a side wall of the cabinet. If desired, additional connecting means may be provided to span the opening between the tops of the two rear corner posts, particularly if a self-contained unit is installed in an existing cabinet, however, completely satisfactory rigidity can be obtained without such additional means. The members 14 and 56 could also be dispensed with if other means are provided for attaching the members 16, for example, if these members are secured to a cabinet wall.

One primary advantage of the form of the invention shown in FIGS. 1 through 8 is that a minimum of parts is employed for achieving maximum function. Thus, the connecting members 16 serve as supporting means for the corner posts, to provide tracks for the drawers, and to provide locking means for holding the drawers in place. The pins 46 and 48 serve as looking pins and as limit means. The side walls 24 perform this function as well as being useful as clamping means in the formation of the drawers.

FIGS. 9 through 12 illustrate alternative designs which may be used in association with corner posts 12 as previously described but which are also ideally suited for mounting in locations having existing structural members. For example, these members in these figures can be attached to walls adjacent an available space whereby the use of the corner posts can be dispensed with. It will also be apparent that members of the type shown in these figures could be used to provide support for one side of a set of drawers while assemblies comprising corner posts 12 and longitudinal members 16 could support the other sides of the drawers.

The member 70 shown in FIG. 9 comprises a side wall 72, top wall 74 and outwardly extending track section 76. The top wall 74 is interrupted by a notch 78 adapted to provide for passage of pins associated with drawers as discussed with reference to FIG. 6. Such notches can, of course, be located at different positions along the length of the wall 74 depending upon the locations of pins provided in the associated drawer.

An angle member 80 is secured to the side wall 72 to provide a stop member for limiting the extent of movement of the drawer relative to the track. It will be apparent that with this arrangement, the drawer will not fall out during use; however, the drawer can be easily removed by lifting it upwardly for passage of an associated pin through the notch 38.

A hole 82 is defined in the angle member 80 and continues through the side wall 72. A fastener can be inserted through this hole for purposes of securing the member 70 to a side wall or to a post or other member situated adjacent the space where the drawers are to be located.

FIG. illustrates a member 84 corresponding with that shown in FIG. 9 including a hole 86 which will provide for fastening of the member to a supporting struc- I ture. In this instance, the stop member 88 is provided by pressing a portion of the side wall 90 inwardly to achieve the necessary abutment which restricts the drawer movement.

In the design shown in FIG. 1 1, the member 94 is provided with a stop member in the form of angle 96. With this design, and with the arrangement of FIG. 10, the

height of the stop member is less than the height of the side wall whereby an opening is defined between the stop member and the top wall 92. With this arrangement, the pins of a drawer will engage the stop member in the normal use of the drawer; however, the drawer can still be readily removed by lifting upwardly and then outwardly for movement of a pin through the passage 100.

FIG. 12 illustrates a further alternative wherein the member 104 is provided with a stop member 106. This stop member is developed by slicing the top wall 108 inwardly for a short distance and then bending a portion of the top wall downwardly to locate this portion in the path of a pin associated with a drawer. A notch 109 is provided in the top wall 108 for passage of pins during insertion and removal of a drawer. It will be appreciated that with all of the designs illustrated herein, pins of the type shown in FIG. 4 could be utilized instead of notches.

In the various members described, the track portions have comprised concave running surfaces which form an ideal track for the convex lower edges of the preferred drawer side walls. Certain novel aspects of the invention can, however, be employed without track portions of this specific design. As illustrated in FIG. 13, the side wall 110 of a drawer may be provided with a longitudinally extending groove 112 adapted to receive the upwardly extending edge 114 of the member 116. In FIG. 14, the member 118 comprises a track portion 120 which is flat for receiving the bottom edge 122 of the drawer side wall 124.

FIGS. 15 and 16 illustrate alternative designs for front and back wall portions of a drawer. It has been found that these alternatives provide for highly efficient drawer manufacture in that the members can be extruded and then cut into individual sections depending upon the size of the drawer desired. The extruding and cutting operations are, of course, relatively simple to carry out whereby the drawer members illustrated can be produced at low cost even though many different size requirements may be involved. Furthermore, the design of the members illustrated is highly important from the standpoint of providing simplified structures for assembly purposes as well as useful structures from the standpoint of the finished drawer.

The front wall member shown in FIG. 15 includes a top wall portion 132 and a downwardly extending handle portion 134. This handle portion includes a return portion 136 whereby no sharp edges are exposed. The lower end of the wall area is divided into sections 138 and 140. The latter section includes an inwardly extending portion 142 located in spaced relationship relative to the section 138.

The member 144 shown in FIG. 16 includes a rounded upper portion 146, and an intermediate bentin portion 148. A lower extension 150 having a right angle bend portion 152 provides a gap 154 which corresponds dimensionally with the gap 143 defined by the front member 130.

The members 130 and 144 are ideally associated with the side wall structure 156 illustrated in FIGS. 17 and 18. This side wall is provided with a routed groove 154 for receiving the front and back walls and for receiving a bottom wall. The front routed area 156 is dimensioned so that the sections 138 and will fit snugly within the groove. Similarly, the return portion 136 is provided with a curvature and dimension for purposes of snugly interfitting with the routed area.

The rounded end 146 and bottom end of the back wall 144 are also designed to be received snugly within the routed groove. Furthermore, a flat bottom wall is employed so that it will bit snugly within the gaps 143 and 154 of the front and back wall members. The described arrangement provides for a highly simplified assembly operation since only a very few steps are required for locating all of the members in position. Suitable adhesives are preferably utilized for maintaining the assembled relationship. Stop pins may be located in the openings 158 by press fitting or by any other suitable technique.

lt will be understood that various changes and modifications may be made in the above described construction which provide the characteristics of this invention without departing from the spirit thereof particularly as defined in the following claims.
